Police: "We hope someone too frightened to speak at the time can find the courage now"

"We are renewing our appeal, five years on, in the hope that someone will have information that could be the key to catching the offender.

“We carried out extensive enquiries at the time of the incident. Unfortunately we were unable to trace the person responsible. We now hope, by renewing the appeal, someone who was too frightened to speak at the time, can find the courage now and speak to us."
